Are you planning to mount the volpot on the board or via (short) wires to the board ?
Low Gain Ratio = 1 + R16/R17
High Gain Ratio = 1 + R16/R19
So 1X gain is usually achieved by leaving out the gain resistors. If R16=1500 than R17 should theoretically have a very high resistance (1,0 mOhm?) and R19=750. Am I wrong?
